I believe those are different voice coils for different speakers. They have done that before at different shows where they had the coils on display of a 16” sub all the way up to the 80” sub.

@@gregaiken1725 there’s plenty of media with infrasonics encoded in it… it’s not often discussed because subs that play into those regions are rare. For the The28, it plays up in to the 600Hz range.

For educational purposes, I wish they had called this the 'Quadrature' Sub. When I sell my first million albums, I am getting 1 in each corner of my rondavel studio.
I like the shape to save space but it looks unstable. Are there special feet that stabilize it or does it attach to the wall securely when 3 are stacked on top of each other?
It actually weighs about 275lbs, so its weight alone really anchors it to the ground. Obviously, you wouldn't want anyone ramming into it when stacked, but as it was described to me, the subs are barely taxed when combined. They practically appear to be paper weights.
Can't afford these,even though Mr.Jeffrey has an unbelievable offering!My Sonodyne monitors,made in India,are $1600 a pair,so 30K is outlandish to me.I will probably go for a Rhythmik,Earthquake Sound or even Golden Ears super subs.Rhythmik would be the first choice.Their infra bass performance might just be second to Ascendo subs,only a lot smaller and around $1000-$3000 across their portfolio I guess!They even have stereo subs and dual driver subs with a crossover from mid to infra region.
No denying that the price point is high, but as he says they are a niche product. We will - eventually - see trickle down. Emphasis on trickle! But it will happen! Thanks for watching!!
Yes it has, and it is a good infrasonic subwoofer, if there were not three issues with it. 1. Noise it creates itself by just operating without any signal. 2. Maximum output level is very limited. 3. Impulse response, and it needs - same as our 80" subwoofer an entire room to operate efficiently.
According to Ascendo's own measurements, the Perlisten D214S has lower distortion at $10K and unbelievably enough..... Four of Hsu's Tn1 subs ($5,200 shipped) still beats the Ascendo sub in distortion. Of course, the Ascendo has more SPL than both the Perlisten and Hsu subs and 4 of the 28's from Ascendo will destroy both the Perlisten and Hsu subs distortion and SPL figures but you have to ask yourself..... and be honest with yourself as well. How much headroom do you actually need when pushing 115db peaks all the way down into single-digits for your room? For me, I have a 350sqft room which means I can buy four of the Hsu TN1's, hit the 115db peaks under 10% distortion at the very least down to 16hz before distortion starts to rise dramatically but at that point, you won't hear it, so..... as much as I'd love to have the money to buy four of the 28's at $120K, there would be little difference in my room between them at the Hsu's at $5,200. But if I had a client with a room big enough and pockets deep enough, I'd certainly be using these incredible subs.

@@dougg1075 Depends on the master, some LFE goes below 20hz, but I don't know exactly how low, I don't think any hollywood film masters contain single hz content that I'm aware of... maybe 12 or 16hz. Many don't even hit 20hz, but 25 or 28. Not much content to take advantage of below 20hz output... a full sized organ can do 16, and there's even at least one that does 8hz... but obviously this is incredibly rare and niche music. So as far as cost/value, obviously it's not there, he acknowledges that. But at least the sub is not just an infra-sub but a "full range" sub so to speak, and the output must be insane. But with how he talked about the power it's capable of using... that goes FAR beyond what a typical home circuit can even deliver even if a circuit was dedicated to each sub... the thing is still going to be power limited lol! Like holy crap. I'd be perfectly happy with a couple good 15"s or 18"s. I mean you could have 4 for 10-20% of the cost of this thing, and 2 for 5-10%, and if they're good subs (even diy but done well), no one is going to say 2 15"s isn't good powerful bass down in the 20s, and potentially even below, and not 95db, but well above 100db depending on the subs and setup, say 105 minimum at 16hz, and potentially 115-120 once you get up over 20hz, and most music content bass is over 25-30hz even in modern genres with synthesized bass sounds. If my avg full spectrum listening level is 85, which is loud for extended periods, then 105+ db sub bass is plenty sufficient, even if like me you like the low bass elevated in level and not merely slightly elevated as though following a gentle downward slope (from left to right, i.e. "flat" response but translated to in-room response/harmon-curve, with natural room gain), but actually boosted above the standard curve... that's still easily achievable and with headroom to spare, and all with just a couple/few thousand watts, something your home circuit can handle. This crazy sub may be nearly distortion free, but when you crank it in a house, there's going to be insane levels of distortion present, not from the sub, but from the house and everything in it, unless you have a really crazily designed dedicated room.
Dude, Bag End has been doing infra for decades and we use them in studios and home installs all the time. I only say this because the video seems to make the case that no one else is doing it and this company is originating the technology, which is false.
Odd, my comment has disappeared. Shame they didn’t discuss more of the technical aspects of the driver. Sensitivity isn’t especially high. Plenty of other woofers doing that - also, they don’t say what impedance it’s into 1w/1m into 8ohm is 2w/1m into 4ohm, 4w/1m into 2ohm, which will skew results. Their own published frequency response shows it’s not as linear as claimed, around 18dB down from 100hz to 20hz. There are car audio subwoofers taking over 30kwrms of power too. Also, the interviewer says we can’t hear below 20hz, we can, we’re just much less sensitive- if we weren’t we’d hear our heart beats and blood rushing through our veins. From Tom Danley: “BTW at 3 HZ the threshold of aubibility is about 125 dB so at 132 dB 3 HZ IS audible!”
its really stupid. fast subwoofers are smaller and lower distortion with less excursion if you also want more spl add drivers all running at low power have your cake and eat it too its so easy and simple

It is stable, dont worry. In those models we used rubber feet for decoupling, hence a little wiggle if you lean on them.
